Time variation of the relative displacements of the five selected areas, magnitude and cumulative number of seismic events. a Time variation of the relative displacements of the five selected areas. Negative displacement implies that the area is moving toward the radar. The vertical interval scale on the time axis starts from 0:00 to 24:00. The time shown as 7:32 a.m. is approximately the time at which the cumulative seismic events exhibited sudden increases. Areas 1–5 are shown in Fig. 3. b Magnitude and cumulative number of seismic events that were determined by Hot Springs Research Institute of Kanagawa Prefecture
